CORPORATION,

PANEL-TRIMMING MACHINE.

Application led June 16,

, about a qua-rter or a third of the way down the panel trimming, whichbead runs across from side to side. This is simply an ornamental device that enhancesthe beauty of the trimming. Not only is the bead formed but the panel trimmin above the bead is of greater thickness a ove the bead than below. The ornamental trimming has heretofore, so far as I am aware, been largely.

done by hand, that is to say, the operator has had to carefully do all the stitching, fixing and riding on an ordinary sewing machine. Ff'oduction has, therefore, been rather slow and the trimming quite irregular. lit is the object of the present invention to provide a suitable attachment to a se-win machine which will permit this work to be one very rapidly and with very much greater precision.

Referring to Fig. 3 and also Fig. 2, the outline of a sewing machine headrwill be apparent with the various devices that go to make up the same. Tt will not be necessary to describe these. in detail as any wellknown sewing machine head can be used.

In Fig. 12 the needle a will be-apparent. This is the ordinary sewing machine with a 8o vertically reciprocating needle. @n the bed of the sewingmachine is located a fiber board guide, which will perhaps be best understood from examining Figs. 9, 10 and 11in connection with the plan view shown 85 in Fig. 1.v Referring to Fig. 1, it will be seen that there is on the left hand side of the machine a guide Now referring to Figs. 4f and 6, it will be seen that this guide b comprises a perpendicularly-folded strip having its top edge turned over in if-like form 1n cross section. This is a guide for the lower end of the paper-board panel that forms the base of the panel trimming of the automobile ,body door and side quarters. a5 The lower edge of this paper-board panel abuts against the vert-ical web of this guide while the turned-over flange b1 at the top holds the paper-board panel from rising up out of the guide. This lower edge guide 10G has a. peculiar construction that makes it both adjustable and releasable from the paper board panel. c designates a rod that runs under the bed d of the machine (see Fig. ll-also Fig. 2). This rod runs through a bracket sleeve e provided with a set screw f and is provided with a handle g. The outer end of the rod is connected by means of an upstanding pin h (Fig. 4) with a yoke z' that fits tightly into the spring barrel y'. A plunger c is guided in said barrel and has its end riveted to a plate m that is secured to the sheet metal lower edge guide b. Obviously by moving the rod c through the bracket sleeve e and setting it with the screw f the normal position of the guide b may be varied to suit the panel boards of varying length, as this moves the slide toward and from the machine head.

The lower edge guide b is also quickly releasable by means of the cord n that passes over the pulley wheel o held inthe bracket p and to the right hand side of the machine and over the pulley wheel Q (Fig. 2). A handle r is within\ convenient reach of the operator so that at any time by a simple jerk down on the handle 1' the panel board lower edge guide b may be released to in sert a new board, or for any other purpose.

The spring s in the spring barrel j quickly returns the guide so that it resumes its normal position. The angle iron slide t (Fig. 6) is provided on the bed of the machine and provided with rearwardly-projecting barrels u which in connection with the headed studs e bolted to the guide b form abutments to limit the outward movement of the guide under the spring project'ion. This slide t is slidable upon theA bed and riveted to the spring barrel y', as is clearly shown in Fig. Il. This mechanism forms a panel board lower edge guide, making it both adjustable and quickly releasable.

Now as to the upper edge guide of the panel board, referring to Fig. 2, it will ybe seen that an abutment v is provided for the upper edge of the main or large panel board to rest against. Now referring to Figs. 9, 10 and 11, the nature of this will be better understood. fw represents a smooth strip of metal laid on the bed al of the-sewing machine. Sweated onto this is the abutment strip 'v This abutment strip is cut away at and y (Fig. 9) to receive the smaller paper board guide z which is secured thereto by means of the screws 1. The screws 2 run through the slots 3 into the bed of the machine dmhence both the large panellboard edge guide and the smaller panel board guide are adjustable bodily within small llmits upon the bed of the-machine (see plan view, Fig. 1). Referring to Fig. 9, it will be seen just how the smaller panel board is guided. The guide a is provided with a bottom that is uncovered at 6 to receive the small paper board which may be rested on this uncovered portion and then slid into the guide pocket 7 which is open at both ends but closed at the sides, as will be evident from comparing Figs. 9, 10 4and 11. This guide pocket is supported by the remainder of the smaller panel board guide above the space 8 which is occupied by the larger panel board when the two panel boards are fed throu h' the machine. Hence this smaller panel oard 'guide acts as a guide and also a locater of the smaller panel board with respect to the larger panel board.

Now turning to Figs. 7 and 8, one may comprehend just the character of work that is intended to be done. 9 designates the smaller panel board which is simply a heavy fiber board. 10 designates a fragment of the larger panel board which it will be understood is co-eXtensive with the inside surface of the door under the window and extends on the machine from theI panel door lower edge guide b to the panel door upper edge guide fv. It is the purpose of the machine to turn a tuck. or fold 11 of the Vtrimming material under the lower edge of the smaller panel board 9 and coincidentally feed a cord 12 in under the trimming material above the tuck and at the lower end of the smaller panel board 9. A shoe 13 serves to turn the tuck or `fold in under1` the panel board 9. This shoe is located with respect to the smaller panel guide as shown in Fig9. First, however, it must be eX- plained how the work is fed to the machine. The larger panel board 10 has already been cut out, the trimming material, usually of velour or velvet, has been cut and clamped to the panel board by spring clamps (not shown). This work is ordinarily done by some one other than the operator ofthe machine. The work is brought in piles of these larger boards with the trimming clamped thereto. The machine operator takes one of the boards with the trimming material clamped thereto, removes the clamps and lays the panel board between the two panel board edge guides and the trimming over the small panel board guide, while the -large panel board is under this guide. He then takes one of the smallerpanel boards and feeds i it through the pocket 7 of the smaller panel board guide z. He then swings th'e shoe 13 down against the forward edge of the material as the same is being fed to the needle. The shoe may be locked in this position as the shoe arm 14 is provided with a segmental slot 15 (Fig. 12) that swings over the screw-threaded stud 17 of the crank 16 (see Fig. 17). All one has to do is to turn the crank part of a tur`n and this releases the shoe arm 14 or clamps it tightly in place, depending upon the direction of the turn. This shoe 13'goes in under the smaller paper board guide z, as is shown in Fig. 9, and earries the trimming. material with it in the form of a tuck or fold 11, as is shown in mechanical function.

Fig. 7. The end of -the shoe extends out beyond the smaller panel board guide e toward the needle and hence guides the trimming material and the tuck and fold to the needle while the tuck is still located under the smaller panel board, as will be evident from Fig. 9.

lVe have not, however, explained how the cord is fed to the rest of the worlr. Referring to the plan view, Fig. 1, it will be seen that there is a spool 18 supported upon a pairv of uprights 19. Upon this spool is wound the cord 2O which passes through the loop-like pipe or cord guide 21 (see Fig.

The guide 21 serves to completely reverse the direction of movement oic the cord, as will beevident from Fig. 8. The lower end of this loop-like cord guide 2l has a clip 22 soldered to it (Fig. 14) and this is screwed to the seat 23, which is a strip that is sweated onto the top of the smaller panel guide e. The bottom of thisv guide 21- opens near its end, as shown at 24, Fig.

v15, and let-s the cord run directly onto the smaller panel. The trimming, of course. has been` passed over the lower portion ofthe cord guide 21.

rlhe work, in substantiall)7 the condition shown in Fig. 7, is fed to the sewing machine head 25, where the needle a penetrates through the trimming.. the smaller paper board panel, the tuck 11. and the larger panel board 10. forming the stitch 26 shown in Fig. 8. This completes the formation ot' the ornamental bead and the thickened portion of the trimming on the anel. p It will be seen that the member .e has a small pocket 7 and a large pocket adjoining this small pocket. 'llie large pocket has no lt is simpljy7 to make the member lighter.
